HERBERT W. ALDEN, OF CANTON, OHIO, ASSIGNOR TO TIMKEN ROLLER BEARINGAXLE COMPANY, OF CANTON, OHIO, A CORPORATION OF OHIO.

ROLLER-BEARING.

Application filed April 15,

To all whom 'it may concern:

Be itknown that I, HERBERT W. ALDEN, a citizen of the United States, anda resident of Canton, county of Stark, and State of Ohio, have inventeda new and useful Imrovement in RollereBearin'gs, of which the followingis a specification.

My invention relates to roller bearings and has for its principalobjects to provide a cage of simple and economical constructioh and ofreat rigidity.

t consists principally in an integral cage comprising a body ortion withsuitable pockets formed there-1n and provided at its ends with annularenlargements.

It also consists in the construction and combination of partshereinafter described and claimed.

In the accompanying drawing, which forms part of this specification, andwherein like symbols refer to like parts wherever they occur, Figure 1is a longitudinal section through a roller bearing having the cage applied thereto; Fig. 2 is. a transverse section on line 22 of Fig. 1;Fig. 3 is an end elevation of the cage, portions being shown in section;Fig. 4 is an edge View of the cage; Fig; 5 is a section on line 55 ofFig. 3; Fig. 6 is a section on the line 66 of Fig. 3; Fig. 7 is an.endwise View partly in elevation and partly sectional of a modifiedform of cage;

ig. 8 is a side view of said modified form of cage; Figs. 9 and 10 aredetail sectional views thereof on the lines 9-9 and 1010, respectively,of Fig. 7.

As illustrated in the accompanying drawings, my cage comprises a hollowconical body portion or shell 1 having longitudinal pockets formedtherein and outwardly extending annular flanfges or enlargements 2 atits ends, all made 0 a single piece of steel. Each pocket is formed bystam ing or pressing outwardly the portions of t e body on oppositesides of the medial line of the pocket. These are severedvfrom eachother longitudinally in the plane of the axis of the cage, and at theirends they are severed from the body portion of the ca e in the planes ofthe inner aces of the end anges; and thus constitute flaps 3 that areintegral with the main body of the cage. The inner surface of each flapof a pair is conical to conform to the roller 4 to be used therein, butthe flap has asli'ghtly greater radius of curvature in order to allowThe several pockets are Specification of Letters Patent.

ture that the axes of the several rollers coincide therewith, and theend flange and. the flaps project outwardly less than the outer portionsof said rollers.

The cage hereinbefore described is designed to cooperate with rollers ofthe type illustrated in Fig. 1. In this figure, the rollers are ofconical form having a groove near their smaller ends adapted tocooperate with a corresponding rib 5 on an inner bearing piece 6, whiletheir. outer bearin piece is a conical shell 7. In assembling t he partsof such a roller bearing, the cage is held in a vertical position withits smaller end down. The several rollers are then placed in theirrespective pockets, and then the inner cone or inner bearing piece isplaced between the several rollers thus nested. The metal flaps of thepockets are sufiiciently resilient to permit the temporary spreading ofthe rollers a sufiicient distance to let the end rib of the cone moveendwise until it snaps into the grooves of the several rollers. When theflaps resume their normal position, the cage keeps them properlyassembled on the inner cone and in proper relation thereto, so that theinner cone may be disengaged from the outer bearing surface withoutafi'ecting'the relation of the rollers to "said cone.

One of the'important advantages of this cage is that it enables thepintles heretofore formed on the ends of the rollers to be dispensedwith. Other advantages of my cage are: its simplicity and economy ofconstruction, its rigidity and strength, its slight friction in service,the facilit with which the parts of the hearing may lie assembled anddisassembled, and itscapacity for maintaining the proper relation of therollers to the bearing cone when the outer bearing shell is separatedtherefrom.

In the modification illustrated in Fi s. 7, 8, 9 and 10, the cagecomprises a conical ody portion or shell 1 and annular flanges 2 at theends thereof, the annular flanges bein on the inner side of the cage.The ca e or s ell has longitudinal pockets, but-the aps 3 at the sidesthereof are pressed inwardly instead of outwardl as in the'form firstdescribed.

What I c aim is:

1. An integral pressed steel cage for a roller bearing comprising endflanges and resilient flaps constituting roller pockets, the said flapsbeing constructed to be moved throughout their entire length relativelyto the end flanges.

2. An integral pressed steel cage for a roller bearing comprising aconical shell having annular flanges at its ends and longitudinal flapsextending outwardly in pairs to constitute pockets, the inner surfacesof said flaps being conical.

3. A roller bearing comprising a conical inner bearing piece, a conicalouter bearing piece, a series of conical rollers between said caringpieces, and an integral cage comprising a body portion havinglongitudinal pockets formed therein for said rollers and annular flangesat the ends of said body portion, the sides of said pockets beingadapted to spread apart when the inner bearing piece is forced endwiseinto osition.

, 4. A roller earing coin rising an integral cage having longitudinalpocke'tsformed therein, rollers seated in said pockets, and a conicalinner bearing piece, the sides of said pockets being adapted to permitthe rollers to spread apart when the inner bearing piece is forcedendwise into position.

5. A roller bearing cage comprising a single piece of steel havingoutwardly extending annular flanges at its endsand pockets in the bodyportion of the cage, said flaps extending longitudinally in the plane ofthe axis of the cage and free at their ends from the body portion of thecage in the plane of the inner faces of the end flanges to formresilient pockets for rollers. a

6. A roller bearing cage comprising a single piece of metal providedwith end flanges and resilient flaps extending between said end flangesand constructed to be deflected throughout their entire lengthrelatively to the end flanges.

7,. A roller bearing cage formed from a single piece of metal comprisingend flanges, and resilient flaps constituting roller pockets betweensaid flanges, the flaps being free from the body of the cage at theirends whereby they may move relatively to the end flanges.

8. A roller bearing cage formed from a single piece of metal comprisingend flanges and resilient flaps constituting roller pockets openingtoward the axis of the cage for the insertion of rollers, the flapsbeing free at their ends, whereby they may move rela-' tively to the endflanges.

9. A roller bearin cage formed from a single piece of meta andcomprising end flanges and roller pockets with resilient sides, thesides of said pockets constructed to.move relatively to the end pieces.

10. An inte ral cage for a roller bearing com rising a flody portionhaving longitudina pockets formed therein with resilient side flaps, andannular flanges, said flaps constructed to move relatively to theflanges.

11. A roller-bearing comprising a conical inner bearing piece having arib near the smaller end thereof, a conical outer bearing piece, aseries of conical rollers between said earing pieces, each of saidrollers having a groove to cooperate with said rib and an integral cagefor said rollers, said cage comprising a conical body ortion havinglongitudinal pockets for said rollers and annular flanges at the endsthereof, the portions of the cage constituting the pockets beingresilie'nt flaps adaptedto spreadapart to per mit the inner bearingpiece to be forced endwise'into position. V

12. A rollerbearing comprising a conical inner bearing piece having a rinear the smaller end thereof, aconical outerbearing iece, a series ofconical rollers between said caring pieces, each of said rollers havinga roove to cooperate with said rib, and a cage for said rollers, saidcage comprising a conical body portion having longitudinal pockets forsaid rollers and annular flanges at the ends thereof, the 'ortions ofthe cage constituting the pockets eing resilient flaps ada ted to bespread a art to permit the inner caring piece to be forced endwise intoposition.

In testimony. whereof I have signed my name to this specification in thepresence of two subscribing witnesses this 8th day of April, 1907, atCanton, Stark county, O.hio.
